The common shiner (Luxilus cornutus) is a freshwater fish of the Cyprinidae family, found in North America. It ranges in length between 4 and 6 inches, although they can reach lengths of up to 8 inches.[1]

Description

The common shiner is silvery colored (sometimes bronze) and has an "olive back with a dark dorsal stripe." [2]

The common shiner is a freshwater fish that can be found in North America. Adults inhabit rocky pools in small to medium rivers. They can live to be approximately 6 years old.[2]

They are considered sexually mature by 7.4 cm. Breeding males have a pinkish tint over most of their body and small bumps or tubercles on their head.[2]

In comparison with other Notropis, the common shiner's head, eyes, and mouth are large.[1]

Habitat

The common shiner can be found in rivers and streams, usually in the faster pools.[clarification needed] It can also be found in ponds and lakes. [2]

Breeding

Common shiners spawn in spring, usually over the nest of a creek chub, river chub, or fallfish, although some males will make their own small nests. Gravel in riffles is also possible.[1] Once the eggs are ready the male guards the nesting site. [2]

Common shiners are known to hybridize with other shiner species.[1]

Diet

The common shiner eats "terrestrial and aquatic insects, vegetation, and other fishes." [2]

Predators

Predators of the common shiner include fish (such as the smallmouth bass and chain pickerel) and birds (i.e. mergansers and kingfishers). [2]
